-/* Model Button
- *
- * GtkModelButton is a button widget that is designed to be used with
- * a GAction as model. The button will adjust its appearance according
- * to the kind of action it is connected to.
- *
- * It is also possible to use GtkModelButton without a GAction. In this
- * case, you should set the "role" attribute yourself, and connect to the
- * "clicked" signal as you would for any other button.
- *
- * A common use of GtkModelButton is to implement menu-like content
- * in popovers.
